Error in last rule"solve_network"

[CUIJING03]

Hi,
My intention is to utilize pypsa-earth in China. Almost all rules are typically strictly enforced, however, the final rule"solve_network" consistently shows a " returned non-zero exit status 1" in the terminal.

Here are the specific error messages.

It's worth noting that I am executing Snakemake through PyCharm, and the only changes I have made are related to adjusting the country code in the configuration file and enabling the "build_cutouts" rule.
